Keyboard key issue
 

Every now and again while flying online (co-op) I lose several mapped keyboard controls. Either landing gear/flaps or...
It is always rather random what stops working. As these are co-op missions there is no hitting refly :(
I first noticed the issue when I installed windows 7 and I was wondering if anyone has any advice.
As I say it is very random, can fly six missions in a row without and issue and then I take off and my flaps do not raise :evil:
I use windows 7 32bit

I can affirm the bug.
Windows 7 64bit Ultimate N

Only while flying online, mostly DF Servers

Every now and then I loose Keybord Input within the game for certain Keys:
G --> Gear
B--> Brakes
F --> Flaps
V --> Flaps
If I 'alt tab' to any other Windows Applikation i can type the charakters F,G,B,V
Other Input like 'CRTL L' for Landing light or 'ALT L' for Position Lights are working fine!

Fokussing back on IL2 I still can´t operate Gear, Brakes or Flaps. Only restart of IL2 solves the lack of input.

Quite annoying ...

I'm still using windows xp, and if I alt-tab out of Il2 and back again, there's always a few and completely random keys that stop responding.
I don't have to restart Il2 though, hitting refly or restarting the mission resolves it.

I've been told that Il2 simply doesn't support alt-tabbing.
